BOSTON — President Obama’s 67-year-old uncle has been released from a Massachusetts jail two weeks after his arrest on a drunken-driving charge — but now his exact whereabouts are unknown, officials said last night.

Onyango Obama was detained by the feds for allegedly violating an order to return to his native Kenya.

Officials declined to say why he was released Thursday.

Fellow residents of his Framingham home and workers at a liquor store where he was deemed a valued employee told The Boston Globe that they had no idea know where he’d gone, and his lawyers were unavailable for comment.

Onyango is a half-brother of the president’s father. Federal officials have said he was ordered to leave the United States nearly two decades ago.
